Recently, I encountered difficulties in selecting a pump. The medium is a flammable and explosive liquid, so reliable sealing is required ； Contains about 15% salt crystals ； There are also trace amounts of gas. The temperature is over 100 degrees Celsius, and the operating pressure is two kilograms. Please provide your valuable suggestions.
Open impeller, double-end pressure-sealing system
With salt crystals present, the isolation sleeve of the magnetic pump might not be able to withstand it.
For low flow rates, a tangent flow pump can be used; the 54+62 solution
Please indicate whether continuous operation is required. If intermittent operation is needed and the frequency is not high, it is recommended to use a pneumatic diaphragm pump with dual diaphragms and an alarm function
Diaphragm pumps are not resistant to high temperatures, which makes it a bit difficult to choose one
Auxiliary impeller with double seals! Learn about the sealing structure on slurry pumps! Since slurry pumps can be used, there’s no problem using yours as well!
The flow rate is stable; a centrifugal pump can be used, with an open or semi-open impeller, and a mechanical seal. The flushing method should be 11+52+62
Looking at the specific values, it mainly affects the material of the gasket. The range of over 100 degrees mentioned by the original poster is too wide; when the temperature exceeds 140 degrees, it becomes difficult to choose an appropriate material
